For example, parasites and germs are things you may not see by bare eyes, but their effects can be life threatening. In this method, clean water should be brought to boil and left at rolling-boil for minutes.
For people living in high altitude areas, it is recommended to boil your water for longer than water boiled at lower altitudes. This is because water boils at lower temperatures in higher altitudes. Boiled water should be covered and left to cool before drinking. For water drawn from wells, leave it for compounds to settle before you filter out clean water for use.
This method uses chemical and physical processes to purify water and make it safe for human consumption. Filtration eliminates both large compounds and small, dangerous contaminants that cause diseases with a simple and quick filtration process..
Since filtration does not deplete all the mineral salts, water that has been filtered is considered healthier compared to water purified using other methods.
Compared to reverse osmosis, filtration is considered effective when it comes to selective elimination of much smaller molecular compounds such as chlorine and pesticides.
The other factor that makes filtration less costly is that it does not require a lot of energy needed in distillation and reverse osmosis. It is an economic method of water purification because little water is lost during purification.
Distillation is a water purification method that utilizes heat to collect pure water in the form of vapor. This method is effective by the scientific fact that water has a lower boiling point than other contaminants and disease-causing elements found in water. Water is subjected to a heat source until it attains its boiling point. It is then left at the boiling point until it vaporizes.
This process removes many contaminants from the water, but it also can remove essential minerals. As a result, many experts do not recommend that people exclusively drink distilled water. Distillation purifies water by using a heat source to vaporize it. When the water becomes a vapor, it separates the liquid from any contaminants or debris that can appear in surface water or groundwater.
The process of distillation is simple. Water has a much lower boiling point than solids and minerals. As such, you can distill water by taking untreated water and heating it until the water reaches its boiling point and starts to turn into vapor.
By keeping the heat at a constant temperature, the water continues to vaporize, but the solids do not. The process also removes microscopic and disease-causing organisms like bacteria and viruses. After all the water is a vapor, you place it in a condenser. When it cools, the water turns back into a liquid.
To ensure the water is free of contamination, people often repeat the distillation process multiple times. People have long experimented with using solar power to distill water. This option is appealing because it is an efficient and eco-friendly alternative to heating water using traditional power sources. However, solar power also has drawbacks when it comes to distillation.
The biggest issue is that it only works for small amounts of liquids. Additionally, the time it takes to distill water multiple times is greater when using solar power than it is when you use a traditional source of power. You might think of swimming pools and water parks when chlorine comes to mind, but it is also a way to purify drinking water. Chlorine has an important purpose in water purification. It has virtually eliminated outbreaks of waterborne diseases in the United States and developed countries around the world.
Chlorine does an excellent job of killing microscopic pathogens that can live in our water supply. Health officials have added chlorine to our drinking water since As a result, cholera, dysentery, and typhoid fever are diseases we think of as old-fashioned illnesses of the Oregon Trail rather than concerns of the modern-day.
Chlorine is the only disinfectant that can effectively kill microorganisms like bacteria during the water treatment process. It also maintains water quality on its journey from the treatment plant to your tap. After decades of research, scientists think that chlorine works by attacking the cell wall of bacteria. They think that exposing a microorganism to chlorine destroys its cell wall by biochemically, chemically and physically changing it. You might be wondering why chlorine can kill microorganisms and not harm humans.
The concentration of chlorine in our drinking water is enough to kill small and simple microorganisms. However, humans are much bigger and more complex, so small doses of chlorine are not enough to harm us.
To keep us safe, water utilities carefully regulate chlorine levels. They make sure they are high enough to kill dangerous microorganisms but low enough to not hurt humans and animals. Doing so ensures that we have safe drinking water for everyone.
Reverse osmosis sounds like a complex scientific term, not necessarily a way to create safe drinking water. However, that is exactly what it can do for us. Osmosis is when molecules pass through a semipermeable membrane from a less concentrated solution to a more concentrated one. Reverse osmosis is simply the opposite. A reverse osmosis system has three canisters. One is the membrane and the other two contain carbon filters.
The first step of water purification using reverse osmosis is pre-filtration. We remove larger sediment and reduce chlorine using a sediment filter, or carbon block filter. This protects the membrane from becoming damaged or clogged. The next step involves using pressure to force water through the semipermeable reverse osmosis membrane.
